Between 2013 and 2021, rates of immunosuppression in adults doubled, according to estimates from a Journal of the American Medical Association (JAMA) research letter.
In 2021, an estimated 6.6 percent of U.S. adults were immunosuppressed. “This rate of immunosuppression was higher than the previous national estimate of 2.7 percent using the 2013 [National Health Interview Survey],” the authors wrote in their paper.
